Script is slow

[JuanRdBO]

I saw in various demo images that the blur script works like a contiuous bur when the current workspace window is closed, but mine works slow. What can I do?

Hey Juan, what is the image size/format that you're using? I've been using the script for a few weeks now, and never had this problem, until I set a PNG wallpaper. Then blurring became slow (even though it's cached?)

Similar problem for me. I put a bunch of time calls in the script to see how long things were taking. With an 8MP background image, it was taking feh around 0.08s to switch the background image on my system. With 10 transition images, this was taking almost a full second.

The two things which worked for me were:

• Reduce the number of transition frames. I changed the script to only use 6 transition frames, and this brought down total time from ~0.9s to ~0.6s for me.

• Scale down the image. I scaled mine from 8MP to 1080p, and it shortened individual feh calls from 0.08s to 0.04s (which brought the total transition time down to ~0.25s.)

I also tried adding -quality 25 to the convert calls, but compression doesn't seem to have a significant impact on how fast feh can change the background image.

Frustrating that I can't get it to transition faster 0.25s, but I'm guessing I'm running up against feh's limitations on my hardware.
